Diacom weirdness & questions

[John Hess]

They were made aware of this problem at least a year ago (on the 86
-that uses the same ECU as you have- and the 89), that I know of.  Here
is the funny part.  I have the Diacom Plus.  I cannot link to the
computer in the ALDL mode;  but, can in the Diagnostics Mode.  If I run
my friend's Diacom (not plus) software, I can link in the ALDL mode with
no problems.  I then exit (without disconnecting any of the software)
and run up Diacom Plus and the system remains linked in the ALDL mode.
With this somewhat cumbersome "workaround", I can use the Diacom Plus in
the ALDL mode.  Advantages?  More data collected faster than in the
Diagnostics mode and the additional graphing capability of the Plus.
